+/*************************************************************************
+ *
+ * The arrows mod adds fancy arrows to the game.
+ * 
+ * Usage: 
+ * /js arrows.sign() turns a targeted sign into a Arrows menu
+ * /js arrows.normal() sets arrow type to normal.
+ * /js arrows.explosive() - makes arrows explode.
+ * /js arrows.teleport() - makes player teleport to where arrow has landed.
+ * /js arrows.flourish() - makes a tree grow where the arrow lands.
+ * /js arrows.lightning() - lightning strikes where the arrow lands.
+ *
+ * All of the above functions can take an optional player object or name as 
+ * a parameter. E.g.
+ * 
+ * /js arrows.explosive('player23') makes player23's arrows explosive.
